The lock operating principle can be divided into establish the sign indicating number, decode, unblank and four processes of return, describe respectively.

One, establishes sign indicating number

If sign indicating number promptly is provided with number, is to be undertaken by the accent code-disc 10 of stirring Cipher mechanism in the lock core structure.During original state, pin 34 positions that recline, control position on return button 33 in the Cipher mechanism and the ratchet 7 on the accurate sign indicating number circle 27 are the zero positions on the accent code-disc 10, in this position, on the ratchet 7 on the accurate sign indicating number circle 27 to sign indicating number breach 35 be in limiting component 29 to code position, promptly with limiting component 29 on the position that harbour 36 is aligned.Ratchet 7 and accurate sign indicating number circle 27 are the parts that unite two into one, and because of being provided with return spring 8 between ratchet 7 and the center shaft coupling 9, and fasten accurate sign indicating number circle 27 by return button 33, and when establishing yard, ratchet 7 and accurate sign indicating number circle 27 will rotate with center shaft coupling 9.When transferring code-disc 10 to rotate counterclockwise a tooth mouth (being that the Arabic numerals that the per tooth mouth all indicates by the natural order arrangement are used as setting number), on the accurate sign indicating number circle 27 of ratchet 7 to sign indicating number breach 35 also just left thereupon with limiting component 29 to code position, promptly left on the limiting component 29 distance to 36 1 ratchets of harbour.When transferring code-disc 10 to be rotated when certain indicates on the digital lattice of Arabic numerals (as number), be stuck in the tooth mouth on the accent code-disc 10 and with the sharp mouth of decide chip 32 front ends and lock number.In establishing sign indicating number, if transfer code-disc 10 to be rotated what tooth mouths, the accurate sign indicating number of ratchet 7 encloses sign indicating number breach 35 is left on 27 and on the limiting component 29 code position (leaving harbour 36) is just equaled to have the distance of what ratchets so.Its decode procedure be exactly with leave on the accurate sign indicating number circle 27 of the ratchet 7 of code position to sign indicating number breach 35, stirring ratchet 7 by thumb wheel sheet 43 again, that it is turned back to is original in code position.Owing to be provided with a plurality of Cipher mechanisms in the lock, when establishing yard, each Cipher mechanism accent code-disc 10 different number (the tooth mouth number of rotation) can be set respectively.

Two, decoding

Figure 4 shows that the original state (referring to Fig. 2) of lock.Thumb wheel sheet 43 shown in the figure is the situations of separating with the position of control gear piece 44 with the position of ratchet 7, obviously can not decode.During decoding, (referring to Figure 10) as shown in Figure 5, must earlier unlocking rod 19 be twisted 90 ° counterclockwise, unlock chip 20 is squeezed to the right open jumper bar sheet 16, jumper bar sheet 16 promotes connecting plates 38 moves right thumb wheel bobbin 48 and control gear piece axle 47, be sleeved on the thumb wheel sheet 43 on the thumb wheel bobbin 48 this moment and be sleeved on control gear piece 44 on the control gear piece axle 47 will be pushed to ratchet 7 on the position that matches of ratchet (control gear piece 44 from the left side of ratchet 7 slip over be stuck on the ratchet along the hypotenuse of ratchet).Then pressing thumb wheel sheet 43 decodes.When pressing thumb wheel sheet 43 (referring to Fig. 6), thumb wheel sheet 43 leaves a ratchet downwards, after unclamping, thumb wheel sheet 43 is return under the effect of return spring, thumb wheel sheet 43 adopts inner bevel design (referring to Fig. 7), make thumb wheel sheet 43 can stir ratchet 7 return the time each time and clockwise rotate a ratchet distance, simultaneously, ratchet 7 must not reverse it by control gear piece 44 stop bits, control gear piece 44 adopts half spacing design, can only rotate, can not upwards rotate (referring to Fig. 8), under the effect of return spring, keep the position that matches with ratchet.Stirring ratchet when adopting thumb wheel sheet 43 returns and rotate this design, is lock internal mechanical motion change to be felt (feel) by thumb wheel sheet 43 time for fear of hand, can strengthen confidentiality.

As shown in Figure 9, when decoding, in order to prevent to make the ratchet return spring be in extreme position by thumb wheel sheet 43 without end and damaged, can on the ratchet of ratchet 7, establish a breach a according to the stroke that ratchet 7 rotates, as remove a ratchet, form a neutral position, when control gear piece 44 when being in neutral position a, in any case thumb wheel sheet 43 is pressed and all can not be stirred ratchet 7 and be rotated further.

When decoding when wrong, unlocking rod 19 back can be twisted, make unlock chip 20 get back to original state, jumper bar sheet 16 returns at this moment, thumb wheel bobbin 48 and control gear piece axle 47 also return are got back to the state of Fig. 4 by Fig. 5.If will decode again, again from original state shown in Figure 4 to decoded state shown in Figure 5.

In decoded state, the string limit 201 of unlock chip 20 can not continue to rotate counterclockwise under the stopping of sewing button 23 near the sewing button 23 of limiting component 29 front ends.

Three, unblank

For each Cipher mechanism, just can realize decoding by pushing thumb wheel sheet 43 according to the number that sets.After all Cipher mechanisms are all decoded, on the limiting component 29 all are on the code position harbour 36, as long as twisting unlocking rod 19 is pushed sewing button 23 aside with unlock chip 20 earlier counterclockwise, make the stepped portions of the slotted eye 311 on the projection 22 disengaging base plates 31 on the sewing button 23, under the effect of return spring 4, limiting component 29 moves right, on it to harbour 36 extend on the accurate sign indicating number circle 27 in the sign indicating number breach 35, sewing button 23 on it moves right with limiting component 29, remove stopping to unlock chip 20, at this moment can continue to twist counterclockwise unlocking rod 19, because unlock chip 20 has the circular arc limit, can remain on twisting unlocking rod 19 under the situation of limiting component 29 location, the pin 13 of stirring drawback lock blade 14 with the outer blade 17 of unblanking on it rotates, make the pin 13 of drawback lock blade 14 move and drive junction plate 5 and dead bolt 1 is inwardly withdrawn along the slotted eye 502 on the junction plate 5 of dead bolt 1, at this moment lock is opened, and door can be opened (referring to Figure 11, Figure 14).

Wrong if decode, not harbour 36 can be on the code position on the limiting component 29, under the stopping of sewing button 23, unlock chip 20 can't continue to rotate counterclockwise, and (referring to Figure 13) can not unblank.

Three, return

After lock is opened, when unclamping unlocking rod 19, dead bolt 1 can outwards eject under the effect of return spring (not drawing among the figure) and go, position (position shown in Figure 13) when outer unblank blade 17, drawback lock blade 14, unlocking rod 19 and unlock chip 20 were all got back to lock and do not opened this moment, at this moment limiting component 29 still is in lockset position of coupler.When shutting the door, dead bolt 1 can be withdrawn again and ejection is gone.As shown in figure 13, when dead bolt 1 withdrawal, be installed in step 121 on the pushing piece 12 of junction plate 5 and will impact projection 171 on the outer blade 17 of unblanking, the outer blade 17 of unblanking is rotated together with unlock chip 20 and unlocking rod 19 clockwises, enter the range of movement of jumper bar sheet 16 when the string limit 201 of unlock chip 20, under the effect of return spring 15, jumper bar sheet 16 can be shifted unlock chip 20 onto the position (referring to Fig. 4, Figure 12) of original state in return.Because jumper bar sheet 16 returns (elasticity of return spring 15 is greater than return spring 4), the jumper bar 6 that is connected with jumper bar sheet 16 will be taken back limiting component 29 position (being to sign indicating number breach 35 is separated on the accurate sign indicating number circle 27 of harbour 36 and ratchet 7 on the limiting component 29) of original state by the pin on the afterbody 2.Thumb wheel bobbin 48 and control gear piece axle 47 also return under the effect of return spring 39,40 simultaneously is sleeved on the thumb wheel sheet 43 on the thumb wheel bobbin 48 this moment and is sleeved on the ratchet that control gear piece 44 on the control gear piece axle 47 also leaves ratchet 7 thereupon and returns original position.When control gear piece 44 and thumb wheel sheet 43 leave ratchet 7, ratchet 7 also return under the effect of return spring 8.That is to say that in case the return spring 15 on the jumper bar sheet 16 obtains discharging, whole system can both self-return.

The mated condition of spring bolt mechanism and lock core mechanism can be represented by Figure 12 to Figure 14.State shown in Figure 12 is the original state of lock, dead bolt 1 is in closed condition, sewing button 23 on the limiting component 29 is positioned at the wind up side on limit 201 of the unlock chip 20 that is fixed on the unlocking rod 19, outer on the unlocking rod 19 13 one-tenth 90 ° of angles of pin on blade 17 and the drawback lock blade 14 of unblanking are established sign indicating number and are carried out at this state; State shown in Figure 13 is decoded state (referring to Fig. 5), at this moment unlocking rod 19 must be reversed 90 ° counterclockwise, utilize unlock chip 20 that jumper bar sheet 16 is backed down the thumb wheel sheet 43 that makes controlling organization and controls ratchet engagement on gear piece 44 and the ratchet 7, so that acting on ratchet 7 with thumb wheel sheet 43 decodes, at this state, as long as decoding is not finished or decoded incorrectly, unlock chip 20 can not be rotated further by the restriction unlocking rod 19 of the sewing button 23 on the limiting component 29, and dead bolt 1 is not subjected to effect still to be in closed condition; State shown in Figure 14 can opening (referring to Figure 11) for the correct lock of decoding, at this moment, because the accurate sign indicating number to harbour 36 and ratchet 7 on the limiting component 29 encloses sign indicating number breach 35 is matched on 27, limiting component 29 and the sewing button 23 on it move right, remove restriction to unlock chip 20, can be rotated further unlocking rod 19, blade 17 is opened dead bolt 1 by unblanking outward.

The application of lock core structure of the present invention is not limited to above-mentioned lock, the lock that also can be used for existing other various structures, only need and to match with limiting component in this lock core structure with the parts of dead bolt interlock, just can control the unlatching of dead bolt, become size of key height, lock that safety is good.
